I have encountered this problem when I try to save big int value by drupal_write_record().
I have defined a field as unsigned big int in the schema, meaning in MySQL I can save value ranging from 0 to 4294967295.
In php, integer value is ranging from -2147483648 to 2147483647.
When I want to save a value like 3453966699, it actually belongs to float type but can be saved as unsigned int(10) not to mention bigint.
But in the drupal_write_record(), all int type including normal and big will be forced to cast to int type.
<?php
if ($info['type'] == 'int'|| $info['type'] == 'serial') {
$fields[$field] = (int) $fields[$field];
}
?>So (int) 3453966699 will become -841000597
Can we make it work with unsigned int and big int?
<?php
if ($info['type'] == 'int'|| $info['type'] == 'serial') {
if ($info['unsigned'] || $info['size'] == 'big') {
$fields[$field] = (float) $fields[$field];
}
else {
$fields[$field] = (int) $fields[$field];
}
}
?>
